Continuous Delivery: Exploratory Lifecycle

Correct Answer: Teams invest in learning and experimentation to clarify requirements

In the Exploratory lifecycle of Disciplined Agile, the early phases are characterized by learning and experimentation to clarify requirements. This is the optimal approach because: The correct answer reflects the core principle of exploratory lifecycles where teams need to discover and understand requirements through active learning and experimentation. The other options are incorrect because: - Following fixed requirements from day one contradicts the exploratory nature and limits the ability to discover better solutions - Strict adherence to initial plans prevents the flexibility needed in exploratory projects - Focusing only on technical implementation while postponing learning activities misses the essential discovery phase needed for project success The exploratory lifecycle specifically emphasizes the need for early learning and experimentation to handle uncertainty and complexity in projects where requirements are not clear at the start.

Correct Answer: To manage high uncertainty while maintaining project control

The Exploratory lifecycle in Disciplined Agile is specifically designed to handle projects with high uncertainty while maintaining control over the project outcomes. This lifecycle recognizes that some projects start with unclear requirements or technology choices, and need a flexible approach to discover the best solution. It allows teams to experiment, learn, and adapt their approach as they gain more understanding of the problem space. The other options are incorrect because: - Establishing rigid requirements upfront contradicts the exploratory nature and agile principles - Following predetermined sequential phases would limit the ability to adapt and explore - Standardized development procedures would not adequately address the uncertainty these projects face The Exploratory lifecycle emphasizes learning and discovery through iterations, making it ideal for research and development projects, or situations where requirements and solutions need to emerge through experimentation.

Correct Answer: They use short experiments to validate assumptions and reduce risk

In the Exploratory lifecycle, teams approach technical spikes through short, focused experiments to validate assumptions and reduce risk. This is the most efficient and agile approach for exploring technical uncertainties. The correct answer aligns with agile principles of quick feedback and iterative learning, allowing teams to gain necessary insights while minimizing time and resource investment. Other approaches are less effective because: Implementing complete features in isolated branches is too time-consuming and resource-intensive for initial exploration. Conducting extensive research and documentation before implementation contradicts the agile principle of rapid learning through doing. Building full prototypes of all solutions is inefficient and wastes resources when simpler experiments could provide the same insights.
